Description

本発明は、道路等の側溝に設けられる雨水集水枡において、集水蓋の下側に取り付けられ、同集水蓋より流下する雨水を集めて排水する側溝用排水装置に関する発明である。 The present invention relates to a drain device for a side groove that is attached to the lower side of a water collection lid and collects and drains rainwater that flows down from the water collection lid in a rainwater catchment provided in a side groove of a road or the like.

一般に図１に示す道路Ｒの側溝には、雨水等を集め、地下に埋設された雨水下水管５に向けて排出する集水枡２が、所定間隔ごとに設けられている。 In general, in the lateral groove of the road R shown in FIG. 1, water collecting basins 2 that collect rainwater and discharge it toward the rainwater sewer pipe 5 buried underground are provided at predetermined intervals.

集水枡蓋１は、雨水等と共に落ち葉や土、小さな異物が流れ込んだとき目詰まりが発生しない程度の大きな目の四角い鉄製格子が採用されている。集水枡蓋１の下には集水枡２があり、集水枡底部には、それらの落ち葉、土砂、異物が雨水下水管５に流入するのを阻止する目的で、溜り部４が設けられており、この溜り部４に雨水が貯留されて蚊などの発生源になっている。 The water collecting lid 1 employs a square iron grid with large eyes so that clogging does not occur when fallen leaves, soil, or small foreign matter flows together with rainwater or the like. There is a catchment 2 under the catchment lid 1, and a reservoir 4 is provided at the bottom of the catchment for the purpose of preventing these fallen leaves, earth and sand and foreign matter from flowing into the rainwater sewer 5. Rainwater is stored in the reservoir 4 and becomes a source of mosquitoes.

集水枡の蚊発生対策として、たとえば特許文献１及び文献２に開示されているような蚊の侵入を防止するために雨水導入バルブやフラップ片が考案されている。しかし、大きな効果を上げるためには団地内全ての雨水集水枡に導入しなければならず、その設置費用が高価すぎるため導入されているところはほとんどないのが現状である。 In order to prevent mosquito intrusion as disclosed in, for example, Patent Document 1 and Document 2, rainwater introduction valves and flap pieces have been devised as countermeasures against the occurrence of mosquitoes in water collecting traps. However, in order to achieve a great effect, it must be introduced into all rainwater catches in the estate, and the installation cost is too expensive, so there is almost no introduction.

特願２０１５−１４７５０は前述の課題を解決するため排水装置自体が網状で蚊の侵入を防止でき、上部を集水蓋とその固定部に挟んで隙間なく固定でき、下部には集水蓋の間を通過し網に溜まった落ち葉、土砂異物が排出できる棒バネ弾性開閉弁が配置された装置で、通常の雨水は網部より雨水枡に流失するが、落ち葉などで網に目詰まりが発生し装置上に雨水が滞留した場合や集中豪雨による大量の雨水が流入し装置上に雨水が滞留した場合、滞留水の自重により弾性開閉弁が開き、落ち葉等と雨水がともに集水枡に流失し、流失後自動的に閉じることができる側溝用蚊発生防止排水装置が提案されているが、弾性開閉弁の開閉力を強く設定すると溜まった落ち葉等が雨水とともに流れにくく、開閉力を弱く設定すると異物の引っ掛かりにより網が開いたままになり蚊の防止機能が発揮できない問題があった。 In Japanese Patent Application No. 2015-14750, in order to solve the above-mentioned problems, the drainage device itself is net-like and can prevent mosquitoes from entering, the upper part can be fixed between the water collecting lid and its fixing part without any gap, and the lower part of the water collecting cover can be fixed. It is a device with a rod spring elastic on-off valve that can discharge fallen leaves and sediments that have passed through the net and discharged foreign matter, and normal rainwater is washed away from the net to the rainwater trough, but the net is clogged with fallen leaves etc. If rainwater stays on the device, or if a large amount of rainwater flows due to torrential rain, and the rainwater stays on the device, the elastic on-off valve opens due to the weight of the accumulated water, and both fallen leaves and rainwater are washed away to the catchment. However, a mosquito-generating drainage device for side gutters that can be automatically closed after being washed away has been proposed, but if the opening and closing force of the elastic on-off valve is set strongly, the fallen leaves that accumulate will not flow with rainwater and the opening and closing force is set weakly. Then, foreign matter is caught Prevention function of the mosquito becomes more remain net open there was a problem that can not be exhibited.

特願２０１５−１４７５０号Japanese Patent Application No. 2015-14750

解決しようとする問題点は、道路等の側溝の集水枡における蚊などの発生を防止する為に簡単な構造で安価な排水装置であり、落ち葉等の管理をしなくてもよい装置を提供することを課題とする。 The problem to be solved is an inexpensive drainage device with a simple structure to prevent the occurrence of mosquitoes etc. in the drainage gutters on the side gutters of roads, etc., providing a device that does not need to manage fallen leaves etc. The task is to do.

前述の課題を解決するため排水装置自体が網状で蚊の侵入を防止でき、上部を集水蓋とその固定部に挟んで隙間なく固定でき、下部には集水蓋の間を通過し網に溜まった落ち葉、土砂異物が排出できる棒バネ弾性開閉弁が配置された装置で、通常の雨水は網部より雨水枡に流失するが、落ち葉などで網に目詰まりが発生し装置上に雨水が滞留した場合や集中豪雨による大量の雨水が流入し装置上に雨水が滞留した場合、滞留水の自重により棒バネ弾性開閉弁が開き、落ち葉等と雨水がともに集水枡に流失し、流失後自動的に閉じることができる側溝用蚊発生防止排水装置において、棒バネを中心付近で分離された２対の部品より作られていて、外側は固定され、内側は固定されていない装置である。 In order to solve the above-mentioned problems, the drainage device itself is net-like and can prevent mosquitoes from entering. The device is equipped with a bar spring elastic on-off valve that can discharge the accumulated fallen leaves and soil foreign matter.Normal rainwater is washed away from the net to the rainwater trough, but the net is clogged with fallen leaves and the rainwater is on the device. If there is a stagnation or if a large amount of storm water flows in due to a heavy rain, and the sewage stays on the device, the spring spring on / off valve opens due to the weight of the stagnation water, and both fallen leaves and storm water are washed away into the catchment basin. In the ditch mosquito generation prevention drainage device which can be automatically closed, the rod spring is made of two pairs of parts separated near the center, the outside is fixed and the inside is not fixed.

本発明は、蚊の外部よりの侵入および、溜り部で発生した蚊の外部への飛び出し防止と、集中豪雨時でも雨水が確実にメンテナンスフリーで下水管に流れることを目的としている。 An object of the present invention is to prevent mosquitoes from entering the outside and preventing the mosquitoes that are generated in the pool from jumping out of the mosquito, and to ensure that rainwater flows into the sewer pipe without maintenance even during heavy rain.

道路側溝の集水枡集水蓋１の下側に取り付けられ、同集水蓋１より流下する雨水を集めて排水する側溝用排水装置において、排水装置８自体が網状であり、上部を集水蓋１とその固定部６に挟んで隙間なく固定でき、下部には集水蓋の間を通過し網に溜まった落ち葉、土砂異物が排出できる棒バネ弾性開閉弁９、１０が配置された装置で、通常弾性開閉弁９、１０は閉じているため、密閉された網８により蚊が雨水枡の溜まり部４に到達できず、産卵を防止する効果がある。通常雨水は網部より雨水枡に流失するが、落ち葉などで網に目詰まりが発生し、装置上に雨水が滞留した場合や、集中豪雨等により大量の雨水が流入し装置上に雨水が滞留した場合、滞留水の自重により弾性開閉弁が開き、落ち葉等と雨水がともに雨水枡に流失し、流失後自動的に閉じることができる側溝用蚊発生防止排水装置を発明した。棒バネ弾性開閉弁は中央部でフリーになっているため、同じ太さの１本の棒バネを使用した時と比べ開閉力は中央部で１／４の開閉力になり、中央部の開閉力を同じ力にした場合、端から１／４の部分での開閉力は１本の棒バネに比べ２倍の開閉力になる。これは、少ない量の雨水により落ち葉などを流すことが可能になり、かつ、流れた後に棒バネ開閉弁を確実に閉めることができ、蚊の侵入を確実に防げることを示す。 In a drainage device for a side ditch that is attached to the lower side of a water collecting basin collecting lid 1 of a road side ditch and collects and drains rainwater flowing down from the water collecting lid 1, the drainage device 8 itself is net-like, and the upper part collects water. A device in which bar spring elastic on-off valves 9 and 10 are arranged which can be fixed without gap between the lid 1 and its fixing part 6 and which can be discharged at the lower part through the water collecting lid and collect fallen leaves and earth and sand foreign matter accumulated in the net. Since the elastic on-off valves 9 and 10 are normally closed, the mosquitoes cannot reach the rainwater pool 4 due to the sealed net 8 and have the effect of preventing spawning. Normally, rainwater is washed away from the net to the rainwater basin, but the net is clogged with fallen leaves, etc., and if rainwater accumulates on the device, or a large amount of rainwater flows in due to torrential rain, etc., rainwater remains on the device. In this case, we have invented a drain device for preventing mosquito generation for side grooves that opens the elastic on-off valve due to its own weight and allows both fallen leaves and rainwater to flow into the rainwater basin and automatically closes after the runoff. Since the bar spring elastic on-off valve is free in the center, the opening / closing force is 1/4 of the opening / closing force in the center compared to when one bar spring of the same thickness is used. When the force is the same force, the opening / closing force at a quarter of the end is twice as much as the opening / closing force of one bar spring. This indicates that it is possible to let fall leaves and the like flow with a small amount of rainwater, and the rod spring on-off valve can be reliably closed after the flow, so that mosquitoes can be reliably prevented from entering.

２対の棒バネ開閉弁の中心部分には網と棒バネを固定するために固定等部分が作られている。固定用部分はシリコンゴム、アルミリング、鉄リングなどを棒バネ先端に取り付けることにより作成できる。 In the central part of the two pairs of bar spring on / off valves, a fixed part or the like is formed to fix the net and the bar spring. The fixing part can be created by attaching silicon rubber, aluminum ring, iron ring, etc. to the tip of the bar spring.

２対の棒バネ開閉弁は中心に向かって下方向に傾斜を持つことにより、落ち葉などが中心一番開閉力の弱い部分に集まりやすくなり、より少ない雨水にて流失しやすくできる。 The two pairs of rod spring opening / closing valves are inclined downward toward the center, so that fallen leaves and the like are likely to gather in the portion where the center opening / closing force is weakest, and can be easily washed away with less rainwater.

集水枡蓋は安全上取り外しができないように固定鎖を設置している場合があるが、その鎖が網とぶつかる部分のみ切ることにより、蚊の侵入を防ぐことができる。 In some cases, the water collecting lid is provided with a fixed chain so that it cannot be removed for safety. By cutting only the part where the chain collides with the net, the entry of mosquitoes can be prevented.

集水蓋１の外形が４６０ｍｍ×４２０ｍｍであり開口部は４３０ｍｍ×３９０ｍｍのため、目合い２ｍｍの小山商事製ポリエチレン網を用いて上部外形４５５ｍｍ×４１０ｍｍ、深さ３００ｍｍで、下部に径２ｍｍ長さ３００ｍｍの網の輪を備えた蚊発生防止排水装置を作った。下部網の輪に径１ｍｍのピアノ線で作成した長さ１５０ｍｍの棒バネ９、１０（中心部バネ定数２Ｎ／ｍｍ）を通し端面の固定１１を行い、間隔１ｍｍに設定された弾性開閉排水口を作成した（図２）。さらに棒バネ中心部に３ｍｍのシリコンチューブを取り付け網固定用部品とした。この装置に１０Ｌ／分で雨水を流したところ滞留水も全くなく流れた。１０Ｌ／分は集水枡が２０ｍ置きに幅４ｍの道路両端に設置されていると仮定し、２５ｍｍ／時間の集中豪雨の時の１つの集水枡に流れる雨水量である。
また、この装置内側に落ち葉を想定し外形６０ｍｍ×４０ｍｍ厚み０．１ｍｍのポリエチレンフィルム５０枚を均一に下部より置き、１０Ｌ／分で雨水を流したところ、約０．５Ｌの滞留水はあったが、弾性開閉弁の中心部隙間が３ｍｍに開きスムーズに排水でき、徐々にポリエチレンフィルムも流失し、１分後には３０枚が流失した。その時滞留水もなくなっていて、落ち葉が雨水と共に流失することが確認できた。Since the external shape of the water collecting lid 1 is 460 mm × 420 mm and the opening is 430 mm × 390 mm, the upper external shape is 455 mm × 410 mm, the depth is 300 mm, and the lower portion is 2 mm in diameter using a 2 mm mesh polyethylene net. A mosquito generation prevention drainage device with a 300 mm net ring was made. Elastic opening and closing drains set with a spacing of 1 mm, with 150 mm long rod springs 9 and 10 (center spring constant 2 N / mm) made through a lower mesh ring and a fixed end 11 (Fig. 2). Further, a 3 mm silicon tube was attached to the center of the bar spring as a part for fixing the net. When rain water was passed through the apparatus at 10 L / min, no stagnant water flowed. 10 L / min is the amount of rainwater flowing into one catchment basin during a torrential rain of 25 mm / hour, assuming that culverts are installed at both ends of a road with a width of 4 m every 20 m.
In addition, 50 polyethylene films having an outer diameter of 60 mm × 40 mm and a thickness of 0.1 mm were uniformly placed from the lower part assuming rained leaves on the inside of the apparatus, and when rainwater was allowed to flow at 10 L / min, there was about 0.5 L of stagnant water. However, the central clearance of the elastic on-off valve opened to 3 mm, allowing smooth drainage, and the polyethylene film was gradually washed away. After 1 minute, 30 sheets were washed away. At that time, the accumulated water was gone, and it was confirmed that the fallen leaves were washed away with rainwater.

上記実施例の下部棒バネを外側は下面より５ｃｍの部分にし、中心部を０．５ｃｍの傾斜を持った構造の装置を作成した。この装置に落ち葉を落とすと落ち葉は斜面に沿って中心部に集まった。 An apparatus having a structure in which the lower bar spring of the above embodiment was formed with a portion 5 cm outside from the lower surface and a center portion having an inclination of 0.5 cm was prepared. When fallen leaves were dropped on this device, the fallen leaves gathered in the center along the slope.
